Purchased in December 2015, my first Honda (first Honda car, I've had an indestructible Honda Rancher for years).
2013 Honda Accord (Black)
Removed clutch slave cylinder delay valve.
Upgraded to Infinity speakers up front with homemade 3/4" MDF spacers, stock rears. Stock headunit with AudioControl LC6i tapped into the front speaker wires, sending signal to a very old MTX amp and 12" Polk MOMO sub.
